DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oscillating sorting surface for sorting and processing grains while placing and transferring a processed material, and to sort the processed material leaking from the oscillating sorting surface from the upper side in the processed material transfer direction. The present invention relates to a threshing apparatus provided with a separation wind supply means for supplying wind.

[0002]

2. Description of the Related Art In a conventional threshing apparatus, an oscillating sorting surface for sorting grains while placing and transferring a processed material is provided substantially continuously in a continuous manner from a starting end to a terminating side in a processed material transfer direction. Have been.

[0003]

Therefore, as the supply amount of the processed material to the swing sorting surface increases, the sorting efficiency of the grains on the swing sorting surface decreases, and the grains cannot be sorted efficiently. Tend. In other words, the processed material on the swing sorting surface is
With the swing of the swing sorting surface, it moves while jumping from the swing sorting surface, and at the time of the jump, the specific gravity is relatively large and the specific grains hard to jump are sorted out from the processed material, Among the processed materials supplied to the swing sorting surface, the upper layer processed material acts as a weight that suppresses the movement of the lower layer processed material, and tries to suppress the jump of the lower layer processed material. The larger the supply amount of, the more the bounce of the lower layer processed material is strongly suppressed, the movement of the processed material as a whole becomes monotonous, and the grain sorting efficiency decreases.

[0004] In order to solve this tendency, for example, it is conceivable to vibrate the swing sorting surface more vigorously as the supply amount of the processed material increases. In this case, however, the drive swing of the swing sorting surface is considered. There is a disadvantage that the dynamic structure is complicated. The present invention has been made in view of the above circumstances, and does not complicate the drive swing structure of the swing sorting surface, and can efficiently reduce the grain even when the supply amount of the processed material on the swing sorting surface is large. The purpose is to be able to sort well.

[0005]

Means for Solving the Problems To achieve the above object, the present invention is characterized by an oscillating sorting surface for sorting and processing grains while placing and transferring a processed material, and a leaking surface from the oscillating sorting surface. In a threshing apparatus provided with a separation air supply means for supplying a separation air to a processing object to be processed from the upper side in the processing object transfer direction, a swing sorting surface is provided with a first grain sieve for separating the processing object by leakage and a second Glen sheave. A step is formed between the rear end of the first Glen sheave and the front end of the second Glen sheave, and a step is provided for dropping the processed material on the lower side in the transfer direction. An opening through which wind can be introduced on the swing sorting surface is formed.

[0006]

[Function] The processed material supplied to the swing sorting surface is sorted while moving on the swing sorting surface. The swing sorting surface is provided with a step portion for dropping the processed material downward in the transfer direction. Therefore, the grains in the processed material are easily knocked down by the impact when the processed material falls from the step and is received by the swinging sorting surface on the lower side in the processing material transfer direction, and the processed material is shaken. With the swing of the moving sorting surface, it is thrown and dropped from the stepped part, and the processed material is received in a state that it is widely dispersed on the swing sorting surface on the lower side in the processing material transfer direction, and the grains are collected. It is less likely that the processed material having a large degree of remaining will fall on the swing sorting surface near the position immediately below the step, and the swing sorting surface can be used efficiently.

[0007] Since an opening through which the sorting wind can be introduced on the swing sorting surface is formed in the step portion, the sorting wind introduced from this opening sorts the processed material falling from the step portion. Not only that, but also by the sorting wind, the processed materials are widely dispersed on the swing sorting surface on the lower side in the workpiece transfer direction, and the swing sorting surface can be used more efficiently.

Further, since the step portion is constituted by the rear end portion of the first grain sheave and the second grain sieve located below the grain portion, the fine sorting operation of the first grain sheave causes the grain located in the lower layer of the processed material layer. Are often dropped. As a result, the processed material in a state where the proportion of straw waste and garbage is increased but the overall processed amount is reduced is thrown onto the second Glen Sheave, and the sorting wind from the opening acts on the processed material, so that the volume is reduced. The wind sorting action of blowing off the non-recovered material with respect to the processed material in a reduced state is further strengthened, and the fine sorting action in the second grain sieve functions better to improve the grain recovery rate.

[0009]

As a result, a step is formed on the swing sorting surface constituted by the Glen Sheave, and the sorting air is introduced into the step, so that the grains in the processed material are easily knocked down. By improving the wind sorting effect at the stepped portion of the processed material whose volume has been reduced due to the grain leakage by the upper grain sieve, the swing sorting surface can be used efficiently, so the supply of the processed material on the swing sorting surface Even if the amount is large,
Grains could be sorted efficiently.

FIG. 1 shows a threshing apparatus mounted on a combine, and a handling chamber A for threshing a harvested culm that is clamped and conveyed from the front side of the machine by a feed chain 1 and a handling chamber A. A sorting device B for sorting kernels from the thresh-processed product subjected to threshing in the room A is provided. In the handling room A, a handling cylinder 2, a receiving net 3 for allowing the threshing product to leak, and a handling room A dust feed port 4 for discharging the threshing processed material remaining in A to the sorting device B side is provided, and the sorting device B is a swinging device for performing the sorting process while transferring the threshing processed material leaked from the handling room A. A sorting body 5 and a garbage 6 for supplying a sorting wind from the upstream side in the processing material transfer direction to the processed material leaking from the swinging sorting body 5 are provided, and collecting units 7 and 8 are provided below the swinging sorting body 5. Are located.

The swing sorter 5 fixes each of the Glen pan 10, the chaff sheave 11, and the straw rack 12 over the upper left and right plates of the sheave case 9, and each of the auxiliary Glen pan 13 and the Glen sheave 14 over the lower left and right plates. And a swing sorting surface 19 for sorting the grains while placing and transferring the processed material is provided. A support shaft 15 is provided on the front side of the sheave case 9, and the support shaft 15 is connected to the machine side. The guide member 16 is supported so as to be reciprocally slidable in a diagonal up-down direction along a guide plate 16 fixed to the sheave case 9, and a rear side portion of the sheave case 9 is supported by an eccentric shaft 17 provided on the body side, and the driving rotation of the eccentric shaft 17 Thus, the swing sorting body 5 is configured to swing in the up-down direction and the front-back direction with the support shaft 15 as a fulcrum.

Then, the processed material leaked from the receiving net 3 is sorted by a specific gravity using a Glen pan 10, then coarsely sorted by a chaff sieve 11 and dropped onto an auxiliary Glen pan 13 or a Glen sieve 14. Is collected by the first thing collection unit 7 as the first thing while being sorted by the sorting wind, is discharged out of the machine, falls over the end of the straw rack 12 or the Glen sheave 11, and is mixed with straw chips and the like. The grain is collected as a second processed product in the second product recovery unit 8 and returned to the handling room A by the slower 18.

The grain sieve 14 is composed of two rectangular wire meshes 14.
The first wire mesh (an example of a first grain sheave) 14a is configured such that each of the first wire meshes 14a and 14b is arranged in the processing object transfer direction in an inclined posture that becomes higher toward the lower side in the transfer direction.
Between the wire mesh and the auxiliary grain pan 13, and between the first wire mesh 14a and the second wire mesh on the lower side in the transfer direction (an example of a second grain sheave).
14b, it is fixed to the sheave case 9 in a state where a stepped portion which falls down in the processing object transfer direction is provided.
In each of these steps, the sorting wind from Karamino 6
An opening 20 capable of being introduced is formed on the second metal meshes 14a and 14b.

Therefore, the grains in the processed material supplied to the auxiliary grain pan 13 or the first wire mesh 14a fall from the step and are knocked down by the impact when being received by the first wire mesh 14a or the second wire mesh 14b. It is easy and the processed objects fall down as they are thrown from the step with the swing of the swing sorting surface 19, so that the processed products are swing sorted by the first wire mesh 14a or the second wire mesh 14b. It is received in a state of being widely dispersed on the surface 19.

In addition, the sorting wind introduced from the openings 20 formed in the step portions not only separates the processing objects falling from the step portions by wind, but also causes the processing objects to be separated by the first wire net by the sorting wind. It is widely dispersed on the swing sorting surface 19 of the second wire mesh 14a or 14a.

Particularly, in the present embodiment, since a step is provided at an intermediate position of the grain sieve 14 in the transfer direction of the processing object and the opening 20 is formed in the step, the processing object supplied to the first wire net 14a is formed. However, compared to the lower-layer processed material in which twigs and the like tend to be caught on the first wire net 14a, the upper-layer processed material that is more likely to move in the transport direction falls before the lower-layer processed material, and before the fall, the upper-layer processed material moves to the upper layer. It is easy for the positioned processed material to be received on the second wire mesh 14b in a state of being located in the lower layer after falling,
Agitation of the processed material in the thickness direction of the processed material layer is promoted.
